I think of the Dread Knight as a "black" Paladin. The Paladin class will most likely to be unavailable to Dark Elves, goblins and Orcs equally Dread Knights will be unavailable to Elves, Dwarves and Halflings.

So take the paladin and reverse the abilities. Paladins help their party by raising moral, Dread Knights harm their foes by lowering moral.
